[Drupal] How to Load Node, File, Taxonomy Entities by ID in Drupal 8?

2 years ago

To load a node details using its id in Drupal 8 use the following syntax:

$node_details = Node::load($nid);

We can load multiple nodes in Drupal 8 using loadMultiple() function. Note that the parameter should be array of ids.

$nodes = Node::loadMultiple($nids);
foreach ($nodes as $node_content) {
  $title = $node_content->getTitle();
  $created_by = $node_content->getOwner();
  $type = $node_content->getType();
  $field1 = $node_content->field_FIELD_NAME->value;
  // Get necessary fileds like this.

If it is a node page, then we can get

$node_content = \Drupal::routeMatch()->getParameter('node');. Similarly we can load file by id and get its contents like this:

$file = File::load($file_fid);
$file_url = $file->url();
$file_name = $file->getFilename();
$url = Url::fromUri($file_url);
$file_user_entity = $file->getOwner()
$file_user_id = $file->getOwnerId()
$size = $file->getSize();
// Getting all other details of the file goes here.

We can load multiple files like node using File::loadMultiple($fids).

For taxonomy term loading we have to pass its target id Term::load($keyword_name->target_id);. We can use getName(), getVocabularyId(), getDescription() etc.

For vocabularies we can use, Vocabulary::load($vid). If there is an object for vocabulary then we can get the vocabulary hierarchy by using $vb_obj->getHierarchy(). Note that we have to use the entity class for appropriate load use Drupal\node\Entity\ENTITY_NAME;. For example:

use Drupal\node\Entity\Node;
use Drupal\taxonomy\Entity\Term;
use Drupal\file\Entity\File;

Hope this helps.

We have added a few new modules to our site recently. Drupal Technical StumbleThis Sean (not verified) access_time 31 Jul 2021 - 06:01 Hi there, I uploaded the files, enabled the modules to use SU, and now I see the link, but there is no icon... How can I fix this? Thanks, Sean webmaster access_time 31 Jul 2021 - 06:01 In reply to Icon doesn't show by Sean (not verified) What do you see when you view the source? Search for stumblethis_button and you should be able to see the code for the image and the URL. Then you should be able to troubleshoot from there.

Most webmasters do not realize this, but a lot of the content on lot of websites can be accessed from multiple URLs. A simple example would be where www.example.com and example.com leads to the same page. This is a fatal mistake in Search Engine Optimization and search engines penalize you for duplicate content. The correct configuration would be where the above two urls will lead you to the same page but example.com will redirect you to www.example.com with a 301 (Moved permanently) status which will not result in search engines penalizing the page. It is very easy to configure 301 redirects using Apache .htaccess file and the process is the same for a Drupal installation also. Drupal Technical Apache htaccess SEO Anonymous (not verified) access_time 31 Jul 2021 - 06:01 Hello. I'm trying to make example.com show as www.example.com, and I'm running into difficulties. I'm on Apache 2.0 and using the following lines in my httpd.conf file: RewriteEngine on RewriteCond %{HTTP_HOST} ^xxxxxxxxxx\.com$ [NC] RewriteRule ^(.*)$ http://www.xxxxxxxxxx.com/$1 [L,R=301] When I go to http://xxxxxxxxxx.com, I get http://www.xxxxxxxxxx.com (as expected). However, when I go to http://xxxxxxxxxx.com/node/1 (it's a Drupal site), I get a 404 thrown and the URL changes to xxxxxxxxxx.com/var/www/drupal/node/1. Same thing with www.xxxxxxxxxx.com/node/1. Any suggestions? I want to run without Drupal's .htaccess file (instead incorporating these calls into my httpd.conf file). webmaster access_time 31 Jul 2021 - 06:01 In reply to Rewrite including filesystem path by Anonymous (not verified) I think the problem is with the base path which results in the redirection to /var/www/ part. The best approach I would think is to start with drupal htaccess and then strip out parts and move to httpd SNVC (not verified) access_time 31 Jul 2021 - 06:01 This is definitely a good guide. Thanks for this. wellyson access_time 31 Jul 2021 - 06:01 This is really nice and helpful.
